3 Claims.

This invention relates generally to builders hardware, and particularly to a unitary construction which can be attached to ventilating doors, such as screen doors, or those of the louvre type, and in the further description, the door will be referred to as a ventilating door, regardless of its construction, the same to be associated with the usual threshold doors of houses or apartments, and an object of the invention is to produce a latch for the ventilating door and to guard an opening in the installation, which opening is intended for the reception of the latch-operating handle of the threshold door; the said device also having an opening through which the usual keyhole of a lock of such door is accessible, the said device having novel means for closing or guarding these openings when the ventilating door is closed and latched.

A further object of the invention is to provide sliding guard which close the aforesaid openings, the said sliding guards being telescopically arranged, one with relation to the other, so that when they are moved to unguard the openings, one slides upon the other for a limited distance, and thereafter, both are moved in unison, the means for accomplishing this result being provided with means by which movement cannot be imparted to the telescopic members until the manually operated means is moved from a seat which it occupies for holding the manually operated means against accidental movement.

A still further object of the invention is to provide a latch bar held normally projected into operative position by resilient instrumentalities at the inner end of the latch bar, the said latch bar being provided with a shoulder engaged by an actuating instrumentality moved as the telescopic members reach their open positions, at which limit of movement the manually operated means is again seated and held against movement until lifted from a retaining means forming a part of the casing of the installation.

A further object of the invention is to provide a manually operated spindle which may be manipulated from the inside or outside of the door, the said spindle operating a link connected 3 to the inner end of the latch bar, which link is retracted and projected under the influence of the rotary movement of the spindle; and furthermore, means are provided for preventing rotation of the spindle, said means being in the nature of a latch which looks the spindle against rotation, the said latch being on the inside of the ventilating door and making it impossible for the spindle to be rotated from without, except by the release of the latch.

A still further object of the invention is to provide means on which the foregoing instrumentalities are assembled and mounted, which mean is bodily installable in the frame of a ventilating door, so that as a unit the locking mechanism and guards for the openings heretofore mentioned, may comprise an article of manufacture, ready for installation by the removal of so much of a ventilating door frame as will accommodate the unit, there being novel means for fastening it on the ventilating door in operative relation to a threshold door.

A further object of thi invention is to provide means for causing the threshold door and the ventilating door to swing in unison by the employment of hinges of novel construction, each of said hinges having a pintle to which one of the leaves of a hinge is secured, whereas the other leaf is hinged on the pintle, the said pintle also having a bracket oscillatable thereon and a spring engaging the bracket for exerting force to swing the bracket on the pintle, it being the purpose of the inventor that brackets of this character shall be attached to the ventilating door so that the said door can be swung into and moved in parallelism with the threshold door, or the ventilating door may be swung independently of the threshold door into an open or closed position.

It is furthermore an object of the invention to provide means by which the threshold door and ventilating door are coupled together when they are parallel and caused to move together by reason of the construction of the hinges of the two doors.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed,

The installation heretofore described comprises a face plate is having an elongated opening, as at H, forming a clearance for the usual knob or lock handle of a threshold door. The face plate has a transversely disposed slot I2, the lower edge of which is provided with notches or seats H and M, into which a lug E5 on a manually operated knob It is alternately lodged so that the said knob cannot be moved until the lug thereof is lifted from the seat or notch E3 or i i. Guard plates ll and i8 are slidably arranged back of the face plate, and the manuaily operated knob 16 is connected to the plate ll by a link. it! which is oscillatable on a pivot 23. The inner surface of the face plate is provided with a plurality of guides 26, 22, 23, 24. The ends of the guard plates travel between guides 2i and 24, and an extension or tongue 25 of the guard plates travels between the guides 22 and 23, so that by these means the guard plates may reciprocate or move with relation to the rear surface of the face plate. The rail 25 which is arranged at right angles to the guide 25 forms an abutment for the edge of the guard plate it when it is moved to a position for closing the opening H in the face plate. The guard plate 3': telescopes the guard plate 53 and passes in front of it during the initial movement, and the guard plate I3 has a pin or stud 2i which is encountered by the plate I? at the end 23 of a slot 23 formed in the plate 5?, and when the end 23 of the set engages the pin or stud 2'5, further movement of the plate ll communicates motion to the plate 58 and both plates are therefore carried to unguard the opening l! in the face plate, and it is understood that the rear plate 33 of the housing has an opening (not shown) coinciding with the opening l l in order that the handle or knob 32 of the threshold door lock may project therethrough. When the guards are to be moved to guard the opening ii, the operating knob I8 is released from the notch i3 the guard i? is moved across the opening H, and when the rear end 33 of the slot 29 encounters the pin or stud 27, motion is communicate to the guard plate It and both plates are moved to closed posit'ons.

The pivot 23 is carried by the plate [1, and the link l9 oscllates on it, and the said pivot is enlarged at its inner end, as shown at 34, and travels in a channel of the latch 35, the said channel having shoulders 35 and 31 at its ends which are abutted alternately by the end 34 of the pivot. The latch bolt 35 has a beveled end 38 which extends through a slot in a flange 15 formed on plate IE9 and engages in a seat 39 located in the door frame so that the latch holds the ventilating door closed and in locked position through means, to be presently explained, but when the plate I! is moved to its wholly open position, the enlarged portion 34 of the pivot abuts the shoulder 3'; of the latch bolt and upon further movement forces the latch to open position against the action of springs 43 which have their ends seated in sockets or recesses 4| formed in an enlarged portion 42 of the latch bolt. The ends of the springs bear against the side 43 of the housing of the hardware. An aperture 44 in the said side forms a clearance for an extension 45 of the latch bolt, and said extension reciprocates in the aperture as the latch bolt operates. The extension 45 has spaced ears 46 and 41, between which one end of a link 48 is pivoted on a pin 49. The end of the link remote from the pivot is connected to a member comprising two spaced plates 53 and 51, each having a slot, such as 52, which receives a part of the spindle, and the said member is slidable transversely of the spindle during the rotation of the spindle. The two plates are connected by a web 53. A cross arm A is carried by the spindle and is adapted to be located between the plates and 5!. The cross arm is substantially rectangular in outline and each short side is arcuate so that as the spindle is rotated, the short side of the cross arm engages "the web and moves the link longitudinally and this action occurs regardless of the direction of rotation of the spindle, since the cross arm engages the web above or below the spindle according to the direction of rotation. The spindle is sectional in character and it comprises a tubular'body portion 54 having an annular rib 55, and the said body portion extends through an aperture of a flange 51 that is integral with the side of the housing, and the body is'held in place loya retaining ring 56 engaging the outer side of the said flange.

The body portion of the spindle is externally threaded, as at 58, and a knob 59 is threaded thereon, and the said knob serves to retain a spring 60 in the :body and tensions the said spring against .a telescopic tubular section El forming a part of the spindle. The end of the body remote from the "knob 59 is lodged in an aperture 52 of a flange or extension 63 integral with the faceplate of the hardware. The tubular section 6'! slides in the body and the spring 60 holds it normally projected outwardly. The tubular section 6! has a knob 54 by which the spindle is turned. The tubular section 61 furthermore has slots 65 and 56, through which a pin 61 extends, the .said pin having its ends lo cated in apertures Bl in the body so that by the assembly illustrated and described, the tubular member may yield .or slide inwardly in order that when the ventilatingdoor and. the threshold door are parallel and in position to be moved to- .gether, the knob E54 will bear against the "threshold door and the space between the two doors will be minimized, and the two doors may be latched together in appropriate way so that they swing in un son The body is furthermore provided with an integral projection 68 having a notch or seat 69 for receiving a lug ll! of a detent H comprising a body carried by a bolt or the like 12, which bolt is slidable in a slot 13 formed in the flange. When the latch bolt has been manipulated to a closed position as it is illustrated in Fig. 9, the detent is moved so that the lug 70 thereof enters the notch 69 and the latch bolt cannot be released until the detent is moved towithdraw the lug from the notch 59, after which the spindle may be turned. The web 53 has a plane or squared outer surface which engages the detent when the latch bolt has been fully withdrawn, and it is shown that the detent H slides in a u-shaped guide 14 stationed on the inner surface of the flange 63 as shown in Figures 17 to 20, inclusive.

The front plate and the back plate are attached together at several points, and the back plate is dished and these plates have integral flanges 63 and 5'! at one end, and these flanges are spaced to form a clearance, between which the frame of the ventilating door is lodged and to which it is secured. The flanges 63 and 57 also embrace the frame of the ventilating door at the edge of a cutaway portion, which cutaway portion provides a clearance for the spindle and the operating parts heretofore described, it being understood that the front plate and the flanges engage opposite surfaces of the ventilating door and are anchored thereto by fastenings, such as screws it, threaded in tubular members ll extending through the front plate, and the tubular members are provided with slotted heads 18 to be en- 6 saged by a screw driver for holding them while the screw is being applied in fastening the parts together (Figures 9 to '12, inclusive).

As shown in Figures 1, 2 and :3, the ventilating door 19 and the threshold .door 8% are hinged so that they may swing independently, or they may be moved to parallel positions and swung as a unit, in which latter position they are connected to move in unison and this may be accomplished by any suitable fastenings between them. Such fastenings may be in the nature of a hook and eye 35A in its simplest form, as shown in Figure 1. door comprises two leaves 13! and 82 secured to the door Jamb and threshold door, respectively, and preferably, the .pintle 83 is secured to one of the leaves by a fastening 8'4 so (Figure 3) that it turns when the door is swung. It is the purpose of the inventors to have the hinge of the ventilating door swingly mounted on an extension of the pintle of the threshold door and, to that end, a bracket-like leaf 85 has a loop or eye 86 inits end which swings on the pintle, and the said bracket has an angularly disposed portion :3! which forms a clearance for a corner of a door jam'b or frame, and the said outer end of the bracket is attached to the ventilating door in known manner. In order to assemble the hinges in operative relation to one another, the stationary leaf of the threshold door is sunk somewhat, as compared with the usual installation, and the hinge for the ventilating door has the angularly disposed portion 8'5 so that it fits in the recessed portion and conforms to the general contour of the surfaces of the door frame or jarnb.

,It is to be understood that any number of hinges maybe provided to suit particular requirements, the weights of the doors and other considerations; and furthermore, the ventilating door has a spring 34" connected to it, which spring is wound around the extension of the pintle and torsionally operates to impart motion to the ventilating door in one direction. The spring is enclosed by a cap 88 secured to the pintle by a fastening 89, such as a screw or the like.
